The effects of different tillage methods on energy consumption and physical properties of soil and percent of germination in canola cultivation

In order to study the effects of different tillage methods on energy consumption¡ physical properties of soil and emergence percentage¡ this research was conducted in Soghan region¡ Orzooyeh township¡ Kerman province of Iran during 2011-2012. The experiment was done as a randomized complete block design with three replications. The treatments of this experiment involved: Chisel plow with two times of harrowing disk¡ cultivator with two times of harrowing disk¡ two times of harrowing disk¡ one time of harrowing disk¡ and control (conventional tillage included of moldboard plow with two times of harrowing disk). The results showed that the conventional methods of tillage significantly increase tillage energy requirements than lowtillage system and treated in a disk with 1427.6 MJ has the lowest energy consumption. The apparent density of soil at 0-15 cm depth has the lowest density of 1.273 g/cm3 and related to double disc treatment. Doubledisc treatment has the lowest average soil particle 31.64 mm. The double-disk tillage treatment has the highest percentage of germination between treatments (average 85.22 %). The low tillage system of doubledisc treatment better and more suitable substrate for germination and root growth of canola provides.
